Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric baking machine for business use in shops and factories that provide waffles and hot sands to customers, and a back side of a baking mold made of aluminum casting having a light weight and good thermal conductivity. Combine the top and bottom baking molds with an electric heater attached to them, put the dough in the middle and bake it sandwiched from above and below, easy to release when taking out the baked product, and on the surface of the baking mold The present invention relates to an electric baking machine in which the durability of a thin fluororesin layer is remarkably enhanced.

[0002]

2. Description of the Related Art Conventionally, when manufacturing waffles and hot sands, the temperature of each baking surface of an electric baking mold having a heater attached to the back side is heated to 160 to 200 ° C., and the top baking mold is rotated upward. After separation, the raw dough is poured into a lower baking mold, the upper baking mold is closed and baked, and then the upper baking mold is opened again upward to take out the product.

[0003] A conventional aluminum casting baking mold that has not been subjected to surface treatment has a surface formed of minute irregularities as shown in FIG. 4. It enters the recesses on the surface of the baking mold and adheres to it, making it difficult to peel off, and applying a release oil to the surface to create an oil film on the baking surface, making it easy to release, but the persistence of the release effect is extremely low, and , The surface is easy to contaminate. Therefore, in the case of continuous use, such as for business use, release oil must be applied each time, which causes a significant reduction in work efficiency.

Also, in order to make products easy to peel off, the mainstream is to apply a fluororesin directly to the surface of an aluminum casting baking mold material. However, if it is used continuously for business use, it will have poor durability. There is a drawback in that the fluororesin thin film is damaged, burnt or peeled, and the product cannot be taken out in a clean state, so that the baking mold must be replaced frequently. The cause is that there are many irregularities on the surface of the aluminum casting.Since the fluororesin is simply applied, the fluororesin thin layer is formed with air remaining in these recesses. This is because the thin fluororesin layer is easily peeled off while repeating heating and expansion and cooling and contraction.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned drawbacks, and is intended to solve the above-mentioned problems. The surface (baked surface) of an aluminum cast baking mold material of an electric baking machine for producing waffles and hot sands is provided. The ceramic fine particles are sprayed at high temperature to form a tough ceramic layer. It was done to do so.

[0006]

In order to achieve the above object, the electric baking machine of the present invention forms a baking mold material such as a waffle or a hot sand with a shape suitable for the purpose of use, such as a waffle or a hot sand, and forms the surface (baking). The surface is smoothed by dispersing ceramic fine particles at high temperature and spraying to form a tough ceramic thin layer, smoothing the surface, and further applying a fluororesin on the upper surface, with a tough ceramic thin layer interposed Electricity for baking food products such as waffles with detachable top and bottom baking molds that have extremely improved the durability of the fluoroplastic thin layer by firmly joining the baking mold material and the fluoroplastic thin layer It was made to provide a ceremony baking machine.

The ceramic fine powder of the present invention comprises a mixture of aluminum oxide fine powder, titanium oxide fine powder and the like, and the ceramic fine particles are melted at a high temperature of 1000 ° C. or higher, and the mixture is sprayed. A ceramic thin layer is formed on the surface (baked surface) to harden and smooth the surface of the baked mold to enhance heat resistance, wear resistance, and corrosion resistance.

[0008] Further, a fluororesin is further applied to the upper portion of the baking die whose surface is smooth and reinforced with a thin ceramic layer as described above to form a thin layer of the fluororesin. The product can be easily taken out without applying edible oil for mold release, and the air layer in the unevenness of the baking mold material is removed by the interposition of the ceramic thin layer, and the fluororesin thin layer is removed. Since it is strongly bonded to the baking mold, it has less damage than conventional products due to the synergistic effect with the ceramic thin layer, is less susceptible to contamination, and can be used for a long time without the need to apply release oil. It is possible to provide an electric baking machine for food having the following characteristics.

[0013]

According to the electric baking machine of the present invention, a baking mold material (1) is formed from an aluminum casting, and the surface (baked surface) is formed.
The surface (fired surface) of a firing mold material (1) formed by casting aluminum fine particles made of aluminum oxide fine powder or titanium oxide fine powder and melting at a high temperature of 1000 ° C. or more and spraying the aluminum casting. By forming a ceramic thin layer (2) having a thickness of about 50 to 120 μm on the surface, a tough and smooth underlayer can be formed. Since the fluororesin thin layer (4) is formed, the surface is extremely smooth as compared with the conventional fluororesin processing only, so that the molds (5A) and (5B) and the product (12) are released. This is extremely easy, and there is no need to apply or spray a release oil, so that the working efficiency can be significantly improved.

Further, since a tough and smooth ceramic thin layer (2) is interposed between the fluororesin thin layer (4) and the baking mold material (1), the baking mold material (1) and the fluororesin thin layer (4) are interposed. ) Are firmly bonded to each other, and the unevenness (3) originally formed on the surface of the aluminum material is smoothed.
When 3) is heated, expansion and contraction are repeated between the baking mold material (1) and the fluororesin thin layer (4), causing a separation phenomenon therebetween, and the fluororesin thin layer (4) is damaged. Although the release effect was reduced and the baking mold had to be replaced in a short time, the unevenness (3) of the baking mold material (1) was reduced by interposing the ceramic thin layer (2) as in the present invention. The air layer (13) in the interior is removed, the fluororesin layer (4) and the baked mold material (1) are strongly joined, and the synergistic effect with the ceramic thin layer (2) is used to form the fluororesin thin layer (4). Since the strength is remarkably increased, it has many features such as being less likely to be scratched, being less susceptible to contamination, and being usable for a long time without applying release oil, as compared with conventional products.
